3 nova PD56 series Process & TeMPerATUre MeTers general FeATUres The PD56 Series of meters combines excellent standard features including a universal input, alarm relay, and a 4 to 2 ma retransmitting output with powerful options including an additional two alarm relays, digital inputs, and RS-485 serial communication including Modbus. Alarm relays All PD56 Series Digital Meters have a standard 3 A Form C (SPDT) alarm relay. Up to two additional 1 A Form A (SPST) relays may be added. All relays can be programmed for a variety of alarm types. High/Low Alarms Set Point Deviation Alarms Fail-Safe and Standby Alarms Relay Delays and Reset Deadbands 4-2 ma retransmitting output A 4-2 ma powered output is standard on all PD56 Series models. The output can be programmed to transmit over any input scale for any input type. Transmitter loop Power supply The 4-2 ma retransmitting output may be configured to provide a 14 to 18 2 ma transmitter power supply. input Bias Adjustment Up to five bias points can be used to provide precise offset adjustments at specific input values. The controller will use the offset to create a smooth input value curve leading up to the bias points. Display Max/Min input values PD56 Digital Meters can record and display maximum and minimum input values. These values will be stored until reset by the user power to the meter is lost. Through the use of the user defined displays, these values can be accessible with the push of the SET/ENT button. serial communications & Adapters Nova meters with the serial communications option can be used for data acquisition or with Modbus communication (RTU and ASCII). Nova meters transmit via RS-485. PDA7485 RS-232 to RS-485 isolated and non-isolated converters and PDA8485 USB to RS-485 isolated and non-isolated converters are available for use with the Nova Multi-Monitoring software or other PC applications. nova Pc software Any Nova Controller with the serial communications option can be configured to interface with the Nova Multi-Monitoring PC software. Up to 3 meters can be monitored and operated, and each can use independent data logging.

The main view screen also displays the basic model numbers of all connected units. Any series of Nova Controllers with the serial communications option may be monitored with this software. Digital input Max/Min reset Two digital inputs can be added as an optional feature. Digital inputs are activated by closing contacts or low logic levels. The configuration of the two inputs can be used to hold or reset the maximum and minimum input values simultaneously or independently. NO switches (external excitation not required) or open collector transistor Simultaneously View Up to 3 Nova Controllers 3

A live updating graph shows PV information as it is logged. Data Acquisition PV data can be logged independently for each meter, and each can have a distinct file name, save location, and logging interval. This data can be graphed using the Data Viewer for quick and clear analysis. Logged data can be exported into spreadsheet format.
